Use the magnitudes of 120 earthquakes listed in the data below. Use technology to find range, standard deviation and variance. If anofher value 7.50 is added to those listed in fhe data set, do the measures of variation change much ?

a) Without the extra data value, the range is ?

b) Without the extra data value, the standard deviation is ?

c) Without the extra data value, the variance is ?

d) With the extra data value, the rande is ?

e) With the extra data value, the standard deviation is ?

f) With the extra data value, the variance is ?

The randes are more than 5% points apart, the variance are more than 5% points apart, the standard deviation are more than 5% point apart, so all of them change significantly
